Linking your website content to your google+ page will help to boost your ranking and traffic to your site.
People overlook this all the time. But the reality is that Google+ is going to find your keywords and plant your post out in front for all to see.
But first you have to ensure that you are writing content with good search engine optimisation (SEO) which includes high traffic, low competition keywords. (Please refer to training on SEO and keywords if unsure - Type what you want to know into the 'NEED HELP bar at the top of the WA site).
It is only natural that Google search engine will highly regard good quality articles and website content that is posted on Google+. So make the most of it and use it.
